F. M ILROY FOLDER FOR ANTISQUEAK MATERIAL Fild July 8. 1950 2 Sheets-Sheet 2 \NVENTOR Fran c L5 8. M lzroy By Attovnqy Patented Sept. 13, 1932 UNITED STATES FRANCIS BERRY MGILROY, OF HAMMOND, INDIANA FOLDER FOR ANTISQUEAK MATERIAL Application filed July 8, 1930. Seria1"No. 466,543.

This invention relates to'improvements in the design and construction of a folder for anti-squeak material, the primary object being to provide a type of folder which con jointly carries cores or beads and enfolds them within the outer edges of a suitable fabric, thus creating an inti-squeak material having edges increased in thickness by the insertion of such cores or beads and at the same time efiecting a channel or concave through the agency of which rivet heads are maintained in a position which assures nonengag-ement with other relative metal parts such as the hood of an automobile, etc.,

With these and other objects in view as will appear as the description proceeds, the invention consists in the design, construction and arrangement of parts as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forming a part of this present application and in which- Figure 1 shows a perspective view of the top of the folder.

Figure 2 shows the outlet of the folder.

Figure 3 shows a perspective view of the under side of the folder.

Figure 4: shows the entrance of the folder.

Figure 5 shows cross-sections at various points in the folder.

Figure 6 shows various stages of the material being folded.

Figure 7 shows a type of finished antlsqueak material.

Referring more in detail to the accompany: ing drawings in which similar characters represent corresponding parts throughout the several views, it will be seen that the invention consists of a casing 10 flat in'crosssection at the entrance 11 and tapering until oval in cross-section at the-outlet 12.

Constructed at the entrance of the casing 10, is a flat or plane section, 13, said plane Constructed on=the under side of the casing 10 aretubes 1'6, spaced a suitable distance apart. These tubesexten'd' from-the entrance 11 toward the outlet 12, said'tubes being disposed to-theinside' upon reaching that por- {7" tion of the casing oval vin cross-section as shown at Band C, Figure 5'. I

At the top of the casing 10, a slot 17 is-cut which facilitates threading the material through the folder,

The folder is provided with a suitable fiange18 providing means for securing-the device to sewing machines.

To efi'ect folding a suitablestripoffabric MI is first inseitedbetween the flat section 13 and the bands 15, one edge of the fabric being foldedi underaround the edge 28. Continuing tothe entrance 11', the tapered casing 10 effects continuousst'ages of'folding as shown ,7 at 20, 21 22 and'23'Figure 6;

During this period of folding, suitable cores which lead through the tubes 1'6, are positioned at the edges ofthe fabric andfol'd ed therein, said fabric and core'sbeing simultaneousl'y. drawn through thefolden,

Positioned in the outlet -12 of the casing and extending inwardly'to the tubes 16 is a horizontal flange 19, through the agencyof which the rough edge 24 is folded under the already folded edge 25,, as the material is 8C drawn through the casing, leaving no rough edges exposed to become frayed.

As already disclosed, the action of the folder creates an anti-squeak web having edges increased in thickness through the insertion 5 i i of cores effecting a channel or concave between such cores.

A further preferred feature is that the folder creates a multipleply' thickness in the base of the anti-squeak, i. e. the grooved section 26 created between the longitudinal cores 27 as shown in Fig.7. 7

The folder may be constructed in varying widths as governed by the-size or the required 9 anti-squeak.

7 It is believed that the design, construction and arrangement of the invention are apparent from the foregoing paragraphs taken in. conjunction with the accompanying drawings without further detailed description.

While the preferred embodiment of the invention has been disclosed, it is understood that minor changes in the details of construc- 7 tion, combination and arrangement of co-opl erating elements may be resorted to within the scope of what is claimed, without departing from the spirit of the invention.

What I claim is:

, 1. In a device of the character described,

10 a casing fiat in cross-section at the entrance and tapering until oval in cr0ss-section at the outlet and a fiat guide plate extending longitudinally from the entrance of the casing, said guide plate being slightly narrower than the entrance.

2. In a device of the character described, a casing fiat in cross-section at the entrance and tapering until oval in cross-section at the outlet, a guide plate extending longitudinally from the entrance of the casing, said guide plate being slightly narrower than the entrance, and bands extending across the guide plate for holding the material thereon.

3. In a device of the character described, a casing fiat in cross-section at the entrance and tapering until oval in cross-section at the outlet, and core insertion tubes on the outer side of said casing extending from the entrance and entering the casing a suitable distance from the outlet.

4. In a device of the character described, a casing flat in cross-section at the entrance and tapering until oval in cross-section at the outlet, core insertion tubes on the outer side of said casing extending from the en trance and entering the casing a suitable distance from the outlet, and a flange disposed in the outlet end of said casing, extending from the outlet to the ends of said core tubes.

In testimony whereof I aflix my signature.

FRANCIS BERRY MOILROY.
